I am looking hardest at the handful of Springfield Armory 1911's that have a mag well. The Loaded Black Stainless Target and the TRP are topping my list.

Canebrake and my own experience made me into a big Tripp Research magazine supporter, but I wonder if their end plate design would do okay in a mag well, or if I have to go with Wilson mags since they don't extend out laterally like the Tripp mags do.

My impression of the WC ETM was that they were trying very hard to respond to the base level quality of the Tripp Research mags. Thanks so much for those photos, Cane! I knew that the Tripp mag's floor plate had that different shape and wondered if it would fit.

It looks very much like it will. Thank you for the suggestion to call Aaron at Tripp to make sure, once I decide on which 1911 to buy. I do know I want a mag well, though!
